Joule Cell Rechargeable Battery by Gosh!

I know most electronics now comes with rechargeable batteries. However, most remotes are still powered by batteries. Although these batteries aren't expensive, they can still add up.

As for me, I'm playing Fatal Frame on my Wii (I know its old, but I WANT TO finish the game) and my wiinote eats up AA battery like a hungry monster. (Say, about 2 every 2-4 days)

SO I started searching online for an "solution" and I finally found the Joule Cell by Gosh!  They cost SG$1.90 per box!!

The 1st impression of the Joyroom D121 Powerbank is that it is very well packaged and looks pretty stylish. The powerbank itself feels solid and the design is simple in an attractive way. It doesn't look or feel cheap.

I did a rough measurement of the powerbank (with ruler since I don't have the tools), the dimension is: ~14.2x7x1.2cm.

The LED display (showing not only the percentage left but also the output/input voltage) is very well done and gave the powerbank a cool and "futuristic" feel to it. I've tested the torchlight function and it turned out to be pretty bright.
HOWEVER, there is one thing I've problem with the product description. I did a little "experiment" on my own and realised that the powerbank is not able to charge my iPhone 6 Plus 3 times as mentioned (in the product description).

I do thing there could be a few possibility that affects the "fairness" of my experiment:

1) My iPhone is jailbroken, meaning it'll consume more battery.
2) I did have some level of usage during the charging period.
3) Bigger screen = more battery consumption

But anyway, I'm going to share what I observe.

I started charging my phone at around 16:00, from 9%. The Powerbank is at 89% then.

Basically, I don't think the Joyroom JR-D121 could charge my iPhone 6 Plus fully for 3 times. 2 times, maybe.

Finally, I'll go to the Pros and Cons.

Digital LED
"Easygoing" as in it can accept most cables I use with it.

Long recharging hours
